On the other hand, you could always respond by saying: I expect not to be asked to do something illegal; I have no interest in working for such a company. However, I have high expectations of you, and that's why I believe I can be fully loyal to you.

Could? sure. Should you expect it? If so, then the industry you work in is systemically corrupt.

I and a co-interviewer recently voted "strong yes" for a candidate partly on the basis of hearing that he took a hard line against giving his CEO access to the text of conversations on a messaging platform.

"I am absolutely going to be loyal to Corpco and its best interests. If I am so much as arrested for my work, regardless of how the trial goes, I can't work for Corpco. If I do something that causes an investigation into Corpco, I will be hurting the company. I left Donoevil because I saw that if I stayed, it would be bad for the company, and I didn't want to be part of that - I wouldn't be showing the loyalty I promised the company. I'm proud of my decision and I wish all the best success to Donoevil."

The problem is that this question often goes unasked so you don't get to answer it you just get evaluated on the perception of this concern.
